    About This Skill

    🔴 Stripe Billing is a Universal Pain. Save 2–4 Days of Manual Setup. Implementing subscription billing, seats, proration, and secure webhook event handling is one of the most tedious tasks for any SaaS founder. This production-ready skill drops a complete, secure subscription engine right into your Next.js application. Why Buy This Skill? - **Signature-Verified Webhooks**: Fully configured signature checking using Stripe cryptography. - **Idempotency Protection**: Webhook event deduplication lookup to prevent processing the same transaction event twice. - **Automatic Seat Syncing & Proration**: Updates Stripe quantities instantly when members are added/removed. - **Dunning Banner & Emails**: Bounces failed payment attempts, tags org as PAST_DUE, and notifies users via console-logged or Resend email alerts. - **SQLite / PostgreSQL Compatible**: Out-of-the-box support for local SQLite development and cloud PostgreSQL (Supabase/Neon) production. Get your SaaS billing configured, tested, and running in minutes instead of days.
